Question

cards marked with number 2to51 are placed in a box and mixed one card is drawn from box .find probability the number on card is an even number

Answer 1

Answer: 25/50 =1/2

Step-by-step explanation:

Samle space number = 50 I.e. number of cards

Even numbers from 2 to 51 are 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50

Total of which is 25

P(even number) = no. of outcomes/total number of outcomes

= 25/50

=1/2

Answer 2

Given:

There are $2 to 51$ cards placed in a box.

To find:

We need to find the probability of the card drawn being an even number.

Step-by-step explanation:

• Here we need to find the probability of drawing out an even number of cards.
• Probability refers to the possibility of occurring an event.

Solution:

Sample space; the total number of cards in the box $= 50$

Now the number of even numbers in the box:

$2,4,6,8,10, 12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50$

Hence there are $25$ total of even cards in the box.

Probability $= \frac{favourable outcomes }{Total number of outcomes}$

Probability $= \frac{25}{50}\\\\\frac{1}{2}\\\\= 0.5$

Hence, the probability of drawing out an even card from the box is $\frac{1}{2}$
